Surveillance video shows woman pull up to car dealership, shoot owner in back of the head

WEST ALLIS, Wis. - Melissa Sandrone is accused of shooting the owner of a Wisconsin car dealership, and witnesses say she then smiled and drove away, according to WITI.

The attack and Sandrone's arrest were caught on camera.

The owner of M&M Motors was filling a tire with air when police say Sandrone pulled up in her Jeep, got out and shot him behind the vehicle. Witnesses say she turned with a smile on her face and drove away.

Surveillance video captured the tense moments:

"A person with a handgun shot my brother and was in my lot staring at us. Very quick. Send an ambulance," the 911 caller said. "Somebody got shot in the parking lot," the 911 caller said. "There's a guy in the shop here. He's bleeding. Shot in the back of the head."

Inside the dealership, people jumped into action. Customers can be seen in the video running to safety as help was called. The store owner was shot in the back and neck but was awake.

"You are so lucky dude," the 911 caller said. "'Do you know the lady who shot you?' No, he doesn't."

Police say Sandrone also fired shots at the worker who followed. Prosecutors say Sandrone may have developed a vendetta for the man she shot, believing he was responsible for a motorcycle crash she was in 14 years ago, but the owner said he did not recognize the woman who shot him.

Dashcam video shows police stopping Sandrone a short time later. They ordered her out of the vehicle and made the arrest.

Police discovered numerous weapons in her Jeep - including an assault rifle, a machete, an ax, a shovel and a plastic tarp.

Melissa Sandrone's arrest

Sandrone's competency tests are expected to be back for a hearing scheduled for April 10th. She is charged with two counts of attempted first-degree intentional homicide, use of a dangerous weapon.
